[vtkusers] Proxy class for vtkUnstructuredGrid

[Sebastien Jourdain]

Sorry to catch up so late, but yes it is possible.
You will need to use the adaptor/generic framework of VTK and create a
bunch of classes that will literally wrap your data structure to the
generic vtk one, specially the way to iterate other the cells.
This framework was meant to support cells that have high order, but it
would be trivial to map any existing cell type and field
interpolation.

you may want to start looking at that:
